Figure 13. Scale-up versus Actual Data.
Based on this actual data, there was not severe rebounding. However, observation of all of the
data show rebound signatures and the over-design was justified. This was a difficult tank to
scale-up. Even with the scale-up, the data results are comparable to the laboratory scale-up
predictions. The procedure, once provided the operating air flow rate, is to:
1 Determine the average velocity (which involved determining the average width based on the
mass in the tank and geometry):
